Hi I can't find a definitive answer but I think it is no. Anyway does anyone know if it possible to do the following?
Get TV out (HDMI) + usb host working at same time
Get usb host (hub or not) + charging the tablet
Get hdmi out + usb host + charging.
I think our tab works with the media dock for the 7" tab but can usb host be added as well? The dock for the note 2 looks amazing and should really be available for all devices like this.
Cheers

I don't know the technical terms behind this but here's the gist of why this won't work: When you are using the HDMI out or the USB OTG it puts the multi purpose connector into a proprietary mode which will I/O a protocol that works with that particular type of device. So when it is in HDMI mode it is using certain data pins to connect with the HDMI pins, and when it is in USB OTG mode it is using some of the same pins to connect to USB data pins.
It can only be in one mode or the other at once, so if you hooked up a hub to a usb OTG connector, or used a USB OTG hub, the jack on the note is going to be in USB OTG mode/protocol, and it will not recognize an HDMI adapter also connected to the hub as an HDMI device that it supports. Only storage devices, HID input devices, and samsung printers are supported on the USB OTG.
Since this is a hardware restriction, I'm 99% sure it cannot be programmed around. I think the same applies to why you cannot charge while using the USB OTG. As far as I know all the HDMI adapters require a usb power source and will somewhat charge the tablet.

Thanks for the info just what I was after, it all sounds like a bummer but not too bad. Sounds like I will need root to connect a ps3 controller then.

No need to root for ps3 controller use. My sixaxis works fine using the standard usb adapter. You'll only need to root if you want bluetooth connectivity.

Bad news, there is no way to enable OTG
Because NS uses usb switch chip FSA9280A, and this chip doesn't support OTG.

I made a mistake, there is a FSA9480 in the phone, so it support OTG in hardware.

I haven't had any luck getting this to work.
I tried hooking up a USB mouse, game pad (wired 360 controller) and a USB flash drive. However nothing happened when I plugged them in.
I connected them using a micro USB to USB adaptor and an externally powered USB hub.
Since the Galaxy Nexus appears to support OTG without issues, I'm guessing it's not working on the NS because of some sort hardware incompatibility.

first of all, are you sure your kernel configure support OTG ?
and then, the "micro USB to USB adaptor " is type-A(pin 4 connected with GND) ?
btw, the cup(S5PC110)'s datasheet shows it support OTG.
Ah, I did not realize there were different types of USB OTG adaptors. Thanks for bringing that to my attention.
I did a bit of digging around and it seems that it's not too difficult to modify the adaptor from type B to type A, provided you have basic soldering ability (http://forum.xda-developers.com/showthread.php?t=1092493). Perhaps I'll give that a go when I get some free time.
Has anyone else tried this feature on NS with any success?
This only applies to the Nexus S i9020.
i9023 seems to user another USB chip (http://forum.xda-developers.com/showthread.php?t=1431151) for which are OTG kernels available:

I'm planning on buying OTG adapter to use usb keyboard/gamepad etc. But is it possible to both charge GTab 2 10.1 and use some usb device if said OTG adapter has multiple usb ports?
Anyone? Help, please :crying:
I know of no such device that will allow for charging and USB keyboard. You may be able to hook up multiple USB devices but no voltage will be passed back to the tablet.
My personal recommendation is to charge via USB and use a bluetooth keyboard. I also recommend patience with the forums.

This may be one of the needed pieces. I use it to connect a 1TB Seagate potable drive. I have seen some hubs but the reviews are not encouraging.

Have you considered Bluetooth. My MS keyboard and mouse connect fine as my Logitech tablet specific ones. I imagine there are BT game controllers too.

PS3 controller comes to mind. I have also used the WII controller to great effect.
Hello, we all know that there are USB OTG Cables with extra power plug (Y cable) but those are supposed to power external device like HDD, DVD, or anything what consumes more power than our android device can handle.
But my question is: is there any USB OTG cable with additional power plug but for simultaneous tablet / phone charging while USB stick is used?
I want to watch something long (i.e. TV Show series) from USB stick via OTG cable but I cannot simultaneously charge my tablet, so if it take too long my tablet will be out of power before I stop watching.

That means I have to add a resistor only to usb connector or just need a different kernel, or both?
On the native firmware say that this support function is disabled. Personally, I use this CivZ-FLEX-ЛУЧ-REV3.6.2 + SphereXtreme, where works flawlessly with OTG + charging resistor 64.9 K.
I call BS!!!!
I have a stock firmware, and have been using all kinds of USB cables. Found the best are made from Sony/Ericson and Blackberry. Once you have a quality cable your charging issues will go away.
Right now I am using a 7 foot cable that is from a Sony. No charging issues and works perfectly.
Lately I found another MHL cable 2hich is called HDMI to Micro HDMI, and that micro HDMI plug looks exactly like micro USB. Will such cable work with Note 8 properly without additional power?
The version of MHL our device supports requires a power source external to the tablet. That means the adapter itself needs to provide the power (battery or power adapter) or can pull enough off the HDMI cable, which is usually not enough juice to run the connection.
MicroHDMI and MicroUSB are also not physically compatible (won't fit the same port and different pin outs) even if they look so much a like. MHL typically uses MicroUSB at one end and full sized HDMI at the other.

This is correct u need to put a 63-65 k resistor between ground and Id pin(pin 4 &5) on USB connector. Doesn't work on civatos 4.4.2 as of now. USB host works fine with regular USB host cable but no charging when u use a y cable. I use civatos 4.2.2 kernel also. Works on yyks note 2 4.3 port also..
I have test multiple times. I use a USB dac in car and need charging and USB host.
what resistor should i use on my sghi257m samsung galaxy s4 mini otg usb cable?
on my dads galaxy s5 Active it shows message that says: Do you wanna enable power sharing
is that OTG? on my S4mini nothing pops up
I know this thread is really old but i want to use a USB DAC so need at cable with a resistor as mentioned above but What ROM should I use now?? also is there anywhere I can buy a cable with resistor in it or do i have to do it myself?
Hello,
I have the TF300T (without the keyboard dock), and I want to get a USB port dongle. However I have two needs:
I want the USB port to provide enough power for a USB 2.5" hard disk. I suppose I can use a powered USB hub for this?
I would really like to be able charge the tablet when the USB dongle is on. Is this possible?
Thank you

If that USB HDD requires 2 USB (one data one power), then a powered hub is your best bet.
When the USB dongle is in, it takes the place of the charging port. You can either charge the tablet or use the dongle.
Hi guys, a friend of mine have and old Samsung android based phone.
I was thinking about give it a better use as an android tv box/media player, but I have a few questions, main concerning USB OTG.
I could use a USB OTG Y cable, so I could charge the phone while using it, and still have the OTG... could I connect an USB hub to the OTG so I could use a USB mini keyboard and a mouse?.
My other problem is the micro usb port and the HDMI conection to the TV. I could use a cable to connect the phone to the TV but then I couldn't connect the USB OTG. It's possible to connect HDMI and still use USB OTG???

Well... just so you know you can't have the phone charging and in OTG mode in the same time. Not even with adapters. This is because the current in USB can't flow in both directions in the same time (because there aren't enough dedicated wires)
